Abstract
The effects of anodization processes on titanium-porcelain bonding were investigated. The morphologies and phase structures were evaluated by field-emission scanning electron microscopy (F-SEM) and X-ray diffraction (XRD). The bonding strength was investigated by three-point flexure test. The corrosion resistance of titanium in artificial saliva was investigated. The SEM results showed that a titanium oxide film with submicron stripes and nano-pores could be prepared by anodization and HF acid pretreatment. This titanium oxide film increased chemical bonding and mechanical interlocking between titanium and porcelain. The anodization process also enhanced the corrosion resistance of the titanium, which led to the increase of corrosion durability of the Ti-porcelain bonding strength.
